About the biodiversity of parasites of freshwater fish from Brazil

The authors analyze the biodiversity of parasites of freshwater fish from Brazil. It is concluded that the number of parasites described so far is low compared to the biodiversity of host species in the country, and that the number of parasites of the different taxa is very variable. An interpretation of these data is suggested, and several recommendations are suggested for the study of fish parasites in Brazil.Univ Porto, Dept Biol, P-4169007 Oporto, PortugalUniv Porto, CIIMAR, Fac Ciencias, P-4169007 Oporto, PortugalUniv Estadual Maringa, Programa Posgrad Ecol Ambientes Aquat Continentai, NUPELIA, BR-87020900 Maringa, Parana, BrazilUniv Estadual Maringa, Programa Posgrad Biol Comparada, NUPELIA, BR-87020900 Maringa, Parana, BrazilUniv Fed Sao Paulo, Dept Ciencias Biol, BR-09972270 Diadema, SP, BrazilUniv Fed Sao Paulo, Dept Ciencias Biol, BR-09972270 Diadema, SP, BrazilWeb of Scienc
